This is a classical and addictive puzzle game called ABCD Connection. It's similar to a 2248 merging game but with much more fun.
Slide the exact words in any of the eight directions (up, down, left, right, or diagonally) to merge them.
Get bigger words when you merge multiple same words together.
Keep merging words to get higher if possible.
Have fun and try this game to develop your IQ.
